Abstract: The present paper deals with fossil plants belonging to 28 genera and 48 species. Fossils were collected from Yingzhuni-anga Formation and Lamaya Formation in Xinlong District, Sichuan province. In this flora the dominant group is Filicopsida (8 genera and 15 species).Of which members of Dipteridaceae, Marattiaceae and Osmundaceae are abundent. Cycadophyta consists of 6 genera and 11 species. Ginkgoales and Coniferales are rich, Pteridospermae consists of Ptilozamites, Lepidopteris and Ctenozamites (1 speciesper genus). The characters of this flora closely resembles Yipinglang flora of Yunnan, Late Triassic flora of Hunan and Jiangxi, Xujiahe and Qinghe of Sichuan, Eastern Xizang, Tonkin flora of Vietnam, Nariwa flora of Japan and East Greenland flora etc. but this flora is younger than the Daqiaodi flora found in Baoding. The age of the flora is assigned to middle Keuper-Rhaetic stage of late Triassic, The climatic of Xinlong District in that time was tropical-subtropical.
